In which situation can a restriction imposed by the state be considered compatible with human rights?

When the restriction is by law, for a legitimate purpose, and applied equally

Human rights protect liberty, but many rights are subject to carefully controlled limitations because the exercise of one person’s freedom can affect public safety or the rights of others. A valid restriction must have a legal basis, pursue a legitimate and necessary public purpose, be reasonable and proportionate, and operate without arbitrary discrimination. It should also remain open to constitutional or judicial review. Option B contains the essential conditions in the question: legality, legitimate purpose, and equal application. Options A and C describe arbitrary or discriminatory power, while D removes accountability and therefore conflicts with rights protection.
